1966 427 head bolt head markings... Picture anyone?

[Steven S.]

Judging manual states "circles on head surface", anybody have a picture of this?

Thanks

The "circle" headmark was used for small block head bolts. Big block bolts had a "cross"

Thanks Joe. I've seen the cross with a number of different letters in the corner, including "O" so I was unclear if that's what the manual was referring to, although it sounds like perhaps they got it confused with the small block head markings.
